If I click No, it returns me to the Ethernet Properties sheet with the multiplexor protocol disabled. If I click Yes, it unchecks the multiplexor protocol and then closes the dialog and property sheet. The googler wasn't very helpful, here.
Uses. Hydrogen peroxide is a mild antiseptic used on the skin to prevent infection of minor cuts, scrapes, and burns. It may also be used as a mouth rinse to help remove mucus or to relieve minor mouth irritation (e.g., due to canker/ cold sores, gingivitis).
Inhalation of vapors, mists, or aerosols from concentrated solutions of hydrogen peroxide can cause significant morbidity. Because it is nearly odorless and nonirritating except at high concentrations, persons may not be aware of its presence. No odor threshold was located for hydrogen peroxide (the OSHA PEL is 1 ppm).
